EDM is by far the easiest and technically best. I myself wouldn't trade my Ramsey FM100B for anything and I have owned an two EDM's, it must be the lights. I have built an FM100B from a kit and it's a challenge.
Those CZH models you can get off eBay and Amazon work good considering you don't need an external antenna. They are easy to use and cheap. All in all if money is an issue I would go with one of them. Actually, two of them, one for a backup.
As long as you stay away from the whole house model you should be in good shape.
I think sound is half the show and it's so easy to get it right with the help from people around here. I credit taybrynn who helped me out a few years back and we get compliments all the time on our sound quality.
